! Purpose:
!   returns a standard atmospheric profile
!
! Input:
!   [stype]   type of profile to return
!             1 = mid-latitude summer
!             2 = mid-latitude winter
!             3 = tropical
!
! Outputs:
!   [hgt]     height (m)
!   [prs]     pressure (hPa)
!   [tk]      temperature (K)
!   [rh]      relative humidity (%)
